Speaking before Canadian Prime Minister Stephen Harper addressed the Knesset, Netanyahu told parliamentarians the Islamic Republic will resume uranium enrichment at a time of its choosing.

"The agreement in Geneva did away with the 20 percent stop, but left the train on its track and enables Iran to upgrade the locomotive by developing new centrifuges so when the day comes, it can leap in a very short time to the final stop on an express track, without stopping at an intermediary stop," Netanyahu said.

He added that the goal must be to take its "nuclear train off its tracks."
